Can anybody tell me if GM has any "desirable" axles out there with a drivers side drop? I'm currently running 12 bolts front and rear in my 88 YJ with a 350/NP203 combo. I'm picking up a 14 FF for my rear and changing up my tranny with a 700R4/NP231, so I'll need a drivers side drop axle. Also models of t-cases does GM make. ie: 205, 203.231,???

NO DONT DO A FORD PIECE. BTW why do you need a drivers side drop? IF you go with an axle that has a drivers side ring gear, go with a mopar product, they are much better than ford and you will not shame the GM with the blue oval piece.

Here is my scenario: 88YJ with a 350/350 TT and an NP203 t-case.(passenger side drop). My axles are GM 12 bolt yes 12 bolt(full width). This set up came from a 78 Blazer. My t-case hangs down way to low and I like the 700R4 because of the low first gear and the overdrive. As for the NP231(GM), I know it has the drivers side drop, which is why I'm looking for that kind of axle. Ultimately I really want a 700R4/Dana300 combo and keep my front axle. I'm a Chevy fan If I go with this route R4/300 what exactly do I have to change? I heard the output shaft of the R4 has to be changed to a 27 spline I beleive. correct me if I'm wrong. Another option is to clock my NP203, I'm still not sure at how to do this. Do I need a clocking ring? Will I have to drill and tap new holes? I've read up about it but I would feel more comfortable with some actual pics and directions.

Anyhow I'm rambling on again, thanx for the reply's and I hope to figure this out soon enough

Thanx in Advance

Get either a Ford HP44 front out of a 77-79 F-250 or get a HP60 out of 77-79 F-350. They will have everything you need. to have a d-side diff. Good Luck

So, if I understand correctly, instead of using a Ford D44 with real wheel bearings, full floating hubs, lockouts, etc, that could even be had with a high pinion and the correct width spring perches to fit his Jeep, you're recommending he use a POS semi-floater CAD unit bearing crap monger axle thats setup for coil springs and links? Fawking NEWBIE moron.

Other than the Ford D44 or 60, there isn't any really good axles. Why not just swap out the transfer case to a 205? Think it costs like $200, if that. That way you can run the axles you got now, or upgrade to the 60 later. BTW, there are no 12 bolt fronts, either 10, D44 or D60. Inless it is custom made.

MOJOMAN... I'm sorry, but you are WRONG . There is no such thing as a 12 bolt front. That's sad. I know more about your truck than you do. And I'm not the sharpest tool in the shed.

Edit: I don't know more about your truck, but I do about your front axle.

Originally posted by MOJOMAN Hey Pope what truck does that combo come out of? And yes I know its a 10 bolt. I'm an ass I know. I never heard of them, whats the info on one of them 241's?

Thanx

241's came in 89-91 Blazer's and Subs. They also came in the pass drp dodges of the same general era, although mating one to a 700 is a little tricky. The 89 model used a mech speed while the later two years used an elec.

The 241 has available for it a SYE kit as well. The lowrange is 2.72:1. It's a plenty stout case, althugh the drop is a little low. I've been working for a while on figureing out a way to clock one, just don't have the $$$$$ to do it.

The HD version of this case was used in the larger Dodges equiped with the Cummins so it can't be all that week

Enjoy, and no, you're not an ass, just a little mis-informed. It happens to the best of us...

Thanx. On another note and a little of topic, What year did the short stainless headers come off of? I heard that they were on the HD2500 series pick-ups in the late 80'S. These are a perfect fit for YJ's with the 350 conversion

Yeah, I was gonna mention the 208/241 also. The 205 is certainly stronger, but the low range sucks (1.96:1), and to mate one to a 700 is a bit pricey; you either have to swap the output shaft (~$150-200 for the shaft, plus completly dismantle the tranny) and use a factory TH-350 version 205 and adapter (figure a few hundred, and some looking); or I've heard you can use a spacer instead of the new shorter output shaft (still have to use the rare factory 205 stuff). The advantages to the 208/241 is that they are cheap, will bolt up to a 700, and have a better low range. They both have slip yokes, there is a SYE kit for the 241, but not the 208. Some have converted them using the rear half of the Dodge 208 case; I looked at doing it and it seemed fairly simple, but I traded my 208 for a 241 and sold off the Dodge 208 parts I had.

pcorssmit, i apologize for my lack of knowledge in the front axle catagory. When i need help with that, i go to my friend who is more knowledgeable and let him help me. He prolly knows a lot more than you though. As for newbie, i dont know everything, but i do know enough not to be called a newbie. Just cause my post count isnt that high i am not a newb. Thanks for your help though.
